Ahmed,

This is the OpenVMS Forum. If you want a UNIX script, it will be more productive to post this question in one of the UNIX or LINUX forums.

Hello Ahmed,

Welcome to the OPENVMS forums, but you probably wanted to be in some Unix forum.

And you proabbly need to fix listener.ora

Just go into the editor and do it?
I guess you have to do this on many systems?

Just use SED -E
or PERL.

Something along the lines of

perl -pie 's/(\(\s*HOST\s*=\s*)\S+/${1}NEWNAME/i' file

That says
-p = loop through input and pritn each line when done
-i = in place replace of output file.
-e = here comes the progra

Look for and remember () a string that starts with
- an open param
- optional whitespace
- the word HOST
- optional whitespace
- and = sign
- optional whitespace
and is followed byt some NON-whitespace (\S+)

Replace ( s/x/y/ ) that all of that, but the remembers (HOST= and the new name.

(untested!)

Enjoy,
Hein,
